Introduction: Student assessment is an effective tool for improving teaching performance. The purpose of this study was to analyze the prosthodontics practical teaching assessment by students of the Institute of Odontology and Stomatology in Cheikh Anta Diop University. Materials and Methods: This was a descriptive and cross-sectional study carried out among 103 students in Master 1 and Master 2 in dentistry. The variables observed included student supervision, preclinical work and evaluation of practical prosthodontics learning. The Likert scale graduated from 1 to 5 allowed a quantitative assessment. SPSS® software version 17.0 was used for statistical analysis. The comparison of averages used Student t-test. The risk of error has been set at 5%. Results: The majority of students (65.1%) found the number of teachers insufficient. Learning objectives were stated for 60.2% of the sample and evaluation procedures were specified for 41.7%. For 73.8% of students, a demonstration was made at each session. The video projector was used according to 69.9% of students. Concerning the certification evaluation, 66% of them disagreed with the final single formula. Conclusion : Given the limitations observed in student assessment, an evalution of its effectiveness would improve teaching performance.

Dental students in programs around the world typically pass preclinical courses before entering the clinic and working on actual patients. Since fixed prosthodontics is a preclinical course that requires a great deal of effort, students may experience a substantial amount of stress that may affect their self-confidence and/or clinical performance. In this study, an instructional video CD (VCD) and study guide depicting the step-by-step procedures involved in a metal-ceramic tooth preparation and provisional crown fabrication was prepared. Students at the Faculty of Dentistry, Tehran University of Medical Sciences, Tehran, Iran, were divided randomly into two groups. Group A students trained as usual with live patients, and Group B students were given a copy of the VCD and study guide following a lecture. The students in Group B were encouraged to read the study guide and watch the VCD after live demonstrations. Then, both groups practiced individually on mannequins. At the end of th...
Evaluating the efficiency of the Dental Teacher system as a digital preclinical teaching tool
Aim: To investigate the use of a preparation evaluation system for enhancing the learning and performance of undergraduate dental students when cutting preparations. Materials and Methods: Two groups of eighteen students each were randomly chosen from the fourth year of the dental programme. The task chosen for this study was to make a cavity in preparation for a mesio-occlusal ceramic onlay in a plastic tooth. The dimensions of the cavity were defined, and 2 burs of known size were used for preparation. For assessment, each tooth preparation was scanned with a digital scanner and analysed using the Dental Teacher software. In the control group, a second corrective preparation was made following the supervisor's instructions. In the test group, the second preparation was made based on Dental Teacher analysis. The final cavities were all scanned and assessed by Dental Teacher comparing the similarity of students' onlay cavity preparations to the ideal preparation. All data were recorded and analysed by the software, including cavity depth and width in the occlusal and proximal box, the extent of mesiobuccal cusp reduction and shoulder width around the mesiobuccal cusp. Finally, the data were statistically evaluated using a Wilcoxon matched pairs test and a Mann-Whitney U test. Results: Three of the 6 cavity dimension parameters improved significantly in the test group whilst no improvement was found in the control group. A positive correlation was found between the improvement and the deviation measured for the first preparations, and it was stronger in the test group than in the control group. Conclusions: The use of Dental Teacher helped students to learn the preparation technique for onlay restorations more efficiently and seems to be a promising and useful method to facilitate their individual performance. Student feedback showed a great demand for digital aids in education.

Introduction: Preclinical dental education promotes development of competency and expertise before students work on patients, but this phase is devoid of exposure to real patients leading to challenges in teaching-learning. Aim: The aim of this study was to explore the challenges faced by students during the process of learning preclinical prosthodontics. Materials and Methods: Two Focus Group Discussions (FGDs) were conducted with two different groups of students and one FGD was held with prosthodontics faculty. The FGDs explored the student's and faculty perceptions on the topics which were difficult for the students to understand and their suggestions on how these topics can be made easier to understand. The discussions were audio taped with prior consent and transcribed. Results: The students and the faculty felt that the subject of prosthodontics is vast, difficult to visualize and also difficult to correlate theory with practical aspects. Lack of clinical exposure coupled with use of conventional methods of teaching were identified as reasons for difficulty in understanding the subject. Both students and faculty members suggested that use of simulation, demonstrations, and videos could augment the learning process for the students. Early clinical exposure will help solve many problems encountered during learning and contribute to a better understanding. Conclusion: The students and faculty expressed a "need" for early clinical exposure to enhance the learner's understanding of the preclinical aspects of the subject. The present study highlights the need for change in instruction methods to enhance the learning experiences in preclinical prosthodontics of dental undergraduate students in India.
PURPOSE: This cross-sectional study aimed to assess teaching staff and their students' perceptions regarding the students' competency for clinical performance following the preclinical fixed prosthodontics course and their suggestion regarding alternative methods to improve the preclinical training. METHODS: Fourth-and fifth-year dental students and their teaching staff participated in a survey about the difficulty that faced the student during transitional period from preclinical fixed prosthodontic training to clinical context at Taibah Dental School. A well-constructed Questionnaire, designed to evaluate the students' perceptions regarding the students' competency for clinical performance following the preclinical fixed prosthodontics course and their suggestion regarding alternative methods to improve the preclinical training. The response to the questionnaire was based on the five-point Likert scale. Medians, frequencies were used to assess their perception on preclinical training and suggestion. RESULTS: A total of 78 students from 90 respond .The survey response was 87%; and 100% for the staff members (9 participants). 46% of the students thought that the four-handed dentistry system is not improving their quality of work and 46% felt that the academic staff were cooperative in helping them.56% of the academic staff members believed that the duration of the preclinical training is sufficient. 78% thought that the theoretical part is closely related to the preclinical training sessions. CONCLUSIONS: The feeling of confidence to start clinical phase felt students and their teaching staff members should be kept and reinforced by improving the positives aspects of the results and to resolve the negativities assigned.
Rethinking Assessment Concepts in Dental Education
International Journal of Dentistry, 2020
Introduction. Dental education involves teaching and assessing the acquisition of verifiable domains that require superior psychomotor, communication, and cognitive skills. Evolving technologies and methods of assessment could enhance student's learning environment and improve tutor assessment experience. e aim of this study was to review the current body of research and evaluate the effectiveness of various methods of assessments in improving learning and performance in preclinical and clinical dental practice. Materials and Methods. A search strategy was implemented using electronic search in major databases. e following key terms, clinical skills, preclinical, dental students, and assessment, were included in the search. Two reviewers independently screened all the articles retrieved following very specific inclusion criteria. Results. e initial search generated 5371 articles and 24 articles were selected for review and data extraction. Cohen's kappa coefficient was used to measure interrater agreement and a score of 94.7% was obtained. Conclusion. Preclinical assessment is an effective tool for promoting skills transfer to clinical phase. Early psychomotor skills assessment is valuable. It allows early intervention in the learning process and assists in effective utilization of learning resources. Technology-enhanced assessment systems allow better patient simulation, enhance learning and self-assessment experiences, and improve performance evaluation. However, these systems serve as an adjunct to conventional assessment methods. Further research should aim at calibrating and integrating these systems to optimize students learning and performance.

Previous research regarding dental students has found modest predictive value in preclinical didactic course grades in predicting clinical performance, but systematic assessment of students' feedback on their perceived preparedness has received little attention as a preclinical assessment methodology. The aim of this study was to assess the perceptions of the dental students at one U.S. academic dental institution regarding their preparedness for clinical performance following the preclinical fixed prosthodontics course. Third-and fourth-year dental students participated in a survey about their perceived preparedness to diagnose and treat patients with fixed prosthodontics needs in the school's dental clinics. The respondents (79 out of 161 students, for a response rate of 49%) rated each item on a five-point Likert scale. Responses about which preclinical procedures of the course prepared students the least and the best were consistent for the third-and fourth-year students. Less than 60% of all responding students felt prepared for planning complex cases and performing laboratory-related procedures. The findings of this study indicate that improvement is required in teaching students about laboratory procedures and problem-solving to adequately prepare them for clinical treatment of patients with fixed prosthodontics needs.
